產品結構
大型三筒烘干機是通過對單筒烘干機的單筒體改為套疊在一起的三筒,以縮短烘干機體的外形尺寸。該機工作時,物料和熱氣流依次進入內至外筒體,在機體Z形往復折流后,充分利用熱能烘干物料后再卸出。
烘干機筒體(ti)部分由三個同軸水平放置的(de)(de)內、中、外(wai)(wai)筒套疊組成,這就使筒體(ti)的(de)(de)截面得到充分的(de)(de)利(li)用。其筒體(ti)外(wai)(wai)形總長度約為與之相當的(de)(de)單筒的(de)(de)30-35%。從(cong)而大幅度地減(jian)少占地面積和廠房(fang)建筑面積。
該(gai)(gai)機的支承裝(zhuang)置,是(shi)在(zai)外筒上輪帶與托輪支承,由電機直接(jie)帶動(dong)托輪。通過托輪與輪帶摩擦,使筒體轉動(dong)。該(gai)(gai)機總體結構緊湊(cou)、合理、簡單(dan),為便于磨損(sun)件的檢修更(geng)換,在(zai)中間設計成軸(zhou)向剖分(fen)式,用(yong)螺(luo)栓固定連接(jie)。
